Title: Sensor device
Inventor: FUJIMOTO KATSUMI
IPC: G01C19/5649
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor device by which not only a rotation angular velocity but also an inclination angle and a linear acceleration can be detected. SOLUTION: This sensor device 10 contains a vibrator 12 which is bending- vibrated by an oscillation circuit 56. The sum of signals which are output from an electrode 26 and an electrode 28 as two detection parts of the vibrator 12 is output from a synthetic circuit 54, and the difference between the signals is output from a differential circuit 58. In a first synchronous detection circuit 60 the output signal of the differential circuit 58 is detected in synchronization with the signal of the synthetic circuit 54. In a second synchronous detection circuit 66, the output signal of the differential circuit 58 is detected in synchronization with a signal having a phase difference of 90 deg. from the signal of the synthetic circuit 54. Respective output signals of the synchronous detection circuits 60, 66 are integrated and then amplified.

Title: Power supply unit for magnetron
Inventor: NAGATA YOSHINOSUKE
IPC: H03B9/10
Filed: 1977-11-11
Abstract: PURPOSE: To ensure the steady supply of the power by securing the automatic gradual increase for the duty cycle of the base current waveform of the switching transistor at the starting time of the magnetron.  
     CONSTITUTION: The commercial frequency power supply of terminal a and a' is rectified (1) to be then applied to primary winding 41 of boosting transformer 4, and switching transistor TR5 intermits the current of winding 41. Thus, the high frequency of the high voltage is obtained at secondary winding 42, and the high frequency is rectified (18) to be supplied to magnetron 19. In this case, the duty cycle of the base current waveform to be applied to the base of TR5 is increased gradually in an automatic way for the period from the throw-in time of the commercial power supply to the lapse of a fixed time in order to give the on/off control to TR5 through comparison 6 between the output passed through constant voltage circuit 7 plus integrating circuit 8 and 9 and the output of saw-tooth wave generator 10.

Abstract: PURPOSE:To prepare fine powder of silicon ceramic raw material having high purity, easily, at a low cost, by reacting an alkali silicate with a mineral acid, mixing the obtained silica with carbon or a carbon compound, and calcining the mixture in a non-oxidative atmosphere. CONSTITUTION:An alkali silicate such as sodium silicate is mixed with a mineral acid such as sulfuric acid to obtain a mixture having an Si concentration of >=15wt%, and reacted under thorough agitation until the mixture becomes non- viscous liquid. The hydrogel thus obtained is filtered, washed with water, and dried to obtain highly pure silica. The silica is mixed with carbon such as carbon black and/or a carbon compound such as sucrose, and calcined at >=1,400 deg.C in reducing atmosphere or at <=1,600 deg.C in nitrogen gas atmosphere to obtain powdery raw material of ceramic composed of SiC or SiN. As an alternative method, the objective product can be obtained by reacting an alkali silicate with a mineral acid in the presence of a carbon source.

Abstract: PROBLEM TO BE SOLVED: To prevent a drive signal from a power source from leaking to a contact part of a signal system even if an ink should attach into between a contact part of the power source and the contact part of the signal system. SOLUTION: Contact parts 42, 44, 46, 47 of a ground system are provided between contact parts 43, 45 of a signal system provided on a carriage and contact parts 41, 48, 49 of a power source system to cut off a short-circuit due to an ink attached to the contact parts of the signal system and those of the power source system. Even if an ink attaches to these contact parts, a leak of ink from the contact parts 41, 48, 49 of the power source system flows to the parts 44, 46, 47 of the ground system, but does not flow to the part 43, 45 of the signal system so that a short-circuit due to the leak of the ink can be cut off. Thus an overvoltage is prevented from being impressed on the contact parts 43, 45 of the signal system.

CONSTITUTION:Alternating-current signals 3 of three phases are inputted also to an arithmetic circuit, and an output obtained by adding up a signal obtained by attenuating an alternating-current signal of a first phase by an attenuator 7 and an alternating-current signal of a second phase and a signal obtained by attenuating an alternating-current signal of a third phase by the attenuator 7 being taken for one phase afresh respectively, signals of six phases in all are inputted to voltage comparators 8g to 8l respectively. Therefore, the voltage comparators 8g to 8l output signal pulses delayed by 1/3<1/2> and ones advanced by 1/3<1/2> from the aforesaid alternating-current signals of three phases respectively. Then, the phase voltages (or line voltages) of a three-phase alternating current thus obtained are converted into pulses by voltage comparators 8a to 8l respectively and the number of pulses (or time intervals of pulses) within a prescribed time is measured by a counter 9. Thereby an output value 10 being proportional to a rotational speed (or a cycle of rotation) can be determined.
